TRANSFERRING MECHANISM FOR METAL RODS OR BARS.

To all whom it may concern:

Be it known that 1,.JEROME R. GEORGE, a citizen of the.- United States residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new are useful Improvement in Transferrin Mechanism for Metal Rods or Bars, of which the following, together with the accompanying drawings, is a specification.

The present invention relates to a transferring mechanism for metal rods or ars and is adapted particularly for the broadside transfer of rods or bars which are advanced in multiple'from the cooling bed of a rolling mill. The mechanism, in the present instance, is shown in cooperation with a central feed table or run-out, upon which successive groups of rods or bars are advanced in multiple from a cooling bed; the

invention contemplates the broadside transfer of such groups, selectively, to parallelfeed tables or run-outs on either side of said central run-out for further operations, such as reshearing, thereon; the transfer to either of said feed tables being accomplished in such a manner that the progress of agroup of'bars already present on either one of said side feed tables, or the immediate advancement of a fresh groiip of bars on the central feed table is not interfered with or delayed.

Other objects-and-advantages of the invention wil l appear from the following description, taken in connection "with the accompanying drawings, in which- Figure 1 is a view in end elevation of a transferring mechanism embodying my in vention. I v

"shown. The conveyer rolls 1 are driven in any well known manner, as by a shaft 4, Fig. 1', connected by gearings 5, 5 with each of said rolls, and may be thrown into andout of operation, as desired; by suitable clutching-mechanism, not shown. on either side of the rolls 1, spaced a suitable distance therefrom, are parallel series of conveyer rolls, 6, 6, which appear only as a single roll on each side of Fig. 1. Each series constitutes a feed table for advancing the bars or rods received fthere on from the central runout. Each set of rolls 6, 6 constituting such a feed tables is suitably supported on a framework? and the rolls are driven in any well known manner, as by parallel shafts 8, connected by gearing 9 with each of said rolls. Rods or bars, assembled in multiple in any well known manner upon the cooling bed, are carried forward in grou s successively by the rolls-1 of the central eed table, and may, if desired, be moved against a fixed stop 10, Fig. 2, the bars bein accumulated in multi 1c arrangement ose to nose upon the ro ls '1, with their forward ends abutting the stop 10.- The mechanism used fortransferring each successive roup ofbars from the rolls 1 of the centra feed table-to the rolls6 of either side feed table will now be described in detail, and since the two sets of mechanism are identical, a

description of one will suffice for both.

Each transfer mechanism is constituted by a plurality of pairs of bar supporting members 11, 12 extending across the space between the 'rolls 1' and one set of rolls- 6, and arranged in alternating relation to the rolls 1, 1 of the central run-out, as shown in Fig. 2, with the inner ends of said members substantially coextensive with the opposite edges of the rolls 1, as shown in Fig. 1. The outer ends of each pair of members 11, 12 are supported on pairs of rollers: 13, 13, journaled on a pin 14 which is supported between the spaced ears of a rocker arm 15 carried by a shaft 16 disposed on the far side of rolls 6, 6. As

shown in Figs. 1 and 2, the pairs of members 11, 12 of the two transfer mechanisms are staggered with respect toreach other, so that they extend in one direction, on one side of each M111, and in the 0 ,posite direction on the other side. The shaft 16 extends approximately the full length of the side feed table, and carries a plurality of these forked rocker arms 15, corresponding in number and position to the pairs of members 11, 12, the ears thereof serving to prevent lateral dis lacement of the ends of the members, and to maintain them on their respective rollers 13. .The shaft 16 is journaled in brackets 17 carried adjacent each roll 6, and is oscillated at intervals through a predetermined arc, by means of a link 18 pivot ally attached to an arm 19 on the shaftand connected to a crank disk 20, on a suitably driven shaft 21. By a suitable clutching mechanism, not shown, the shaft 21 can be rotated in either direction, to bring the shaft 16 into the position desired; in one extreme position of said shaft, as shown at the lefthand-end of Fig. 1, the upper surfaces of members 11, 12 are disposed above thesupporting surfaces of the rolls 6; in the other extreme position, which is the normal operating position of the members 11, 12, with respect to the rolls 6, as shown at the right hand end of Fig. 1, in connection withthe otherside of the feed table, the upper surfaces of members 11, 12 are disposed below the supporting surfaces of the rolls6..

A shaft 22, supported in brackets 23 carried b the framework 2, extends longitudinaily of the central run-out on the same side thereof as the corresponding sets of conveyor members 11,12. Secured to this shaft are a series of alined rocker arms 24 which provide alined 'ournals for a shaft 25 parallel to the sha t 2 2, and extending the-full length of the central run-out. At intervals onshaft 25, corresponding to the disposition of the pairs of members 11, 12,

are provided pairsof eccentrics 26, 27, one

for each member, one eccentric of each air being dis osed de' rees in advance 0 the other. he straps 0 said eccentrics have extensions30 bolted or otherwise secured to the res 'ective member 11 or 12, as shown at 31, ig. '3. The shaft 25 has secured thereto a gear 32, in mesh with an idler ear 33 loosely j'ournaled on shaft 22. The atterv ear meshes with a gear 34, which is driven by a pinion 35 onthe' shaft of a gear 36;, which is in turn driven by apinion 87,011 the shaft of a motor or other prime mover 38. As shown, themechanism above described is provided in connection with each set of members 11,12

on opposite sides of the central runout.

In this manner the power of the, motor is transmitted to the corresponding pairs of members 11, 12, causing the inner end of each member to describe a true circle, of a radius depending upon the eccentricity of its connection with shaft 25. 'This result follows from the free movement of the outer end of each member back and forth'on its roller 13, as heretofore described; it will be clear, moreover, that the angular arrangement of the driving eccentrics for each pair of members on the shaft 25 results in a relative shut-Hing movement in which they describe identical paths, one in advance of the other; in other Words, all the mem bers 11 travel to etherin the same path, while all the mem ers 12 travel together in similar paths 180 behind members 11.

Each shaft 22 carries an arm 39, pivotally connected to a link 40 which is actuated by an eccentric 11 on a shaft 42. The two shafts 12 are independently rotatable, by suitable clutching mechanism, not shown, to rock the shafts 22 independently at selected times, carrying the eccentric shafts extreme position as shown on the right hand side of Fig. 2, the inner ends of the members 11, 12 are disposed above the supporting surfaces of the rolls 1.

The operation of the mechanism thus far described will now be set forthin connection-with one side of the transfer mechanism; for example, the members 11 and 12 on the right hand side of the central runout. Referring only to the operation of this one side, during 'theadvancement of a multiplicit of bars on the rolls 1, as shown at 43, Fig.6, the shafts 21 and 42 are so disposed that the corresponding ends of mem ers 11, 12 are below the supporting surfaces of rolls 1 and 6 respectively, as shown in Fig. 6.- After agroup of bars has been run out on the central feed table, the shaft 42 is rendered operative, to shift momentarilythe ends of members 11, 12 above the surface of rolls 1, as shown in Fig, 7 and simultaneously with this shiftin t they will be carried outwar ly, and just as the circular path traversed b the bar supporting port on of saidmem ers 11- begins its inward movement, the whole group oi bars is picked off by the other members 12 which owing to. the angular dis'placemeni of the eccentrics 26, 27, are at this time jus beginning the upward and outward ortioi of their ci cul m eme t. T e s a t 45 is immediately returned to its normal posi tion from which it was rocked momentarily as above described, thereby carrying the inner ends of members 11, 12 whose shuflling movement continues, below the surfaces of rolls 1, as shown in Fig. 8, thus permitting the advancement of another set of bars, indicated at 44, Fig. 8, onto the rolls of the central run-out. The action of the motor 38 continuing, as above set forth, the group of bars 43 is gradually conveyed, step by step toward the side run-out rolls 6, being alternately supported first on the members 11 and then, on the members 12, and making its traverse in paths a proximating a semicircle, always above tie intermediate positions assumed by said members, i. 0., when members 11 and 12 lie in the same plane. In the meantime, a new group of bars is advancingon the central runout rolls 1, as shown at 44, Figs. 9 and 10. As shown in Fig. 9, the group of bars 43 finally reaches, by the continued shuffling movement of the members 11 and 12 the vicinity of the rolls 6, where the broadside movement is halted by a stop the next step in the movement of the bars will carry them over the rolls 6, and at this point, the shaft 21 is thrown into operation, rocking the shaft 16 and lifting the ends of members 11 and 12 clear of said rolls, as shown in Fig. .10. The members are thereafter returned to normal position by the reverse rotation of shaft 21, allowing the bars 43 to be received upon the rolls 6, and run out, by said rolls, in multiple, for a reshearing operation, or otherwise dis osed of, in any usual manner. As soon as t e following group of bars 44 is sufiiciently advanced on the central runou't, the m mbers 11 and 12 are again momentarily lifted'at their inner ends by rotation of the shaft 42 to pick the bars oil of the run-out and start their broadside travel, in the manner above described.

In the use of two transferring mechw nisms, and two side run-outs, as shown in Fig. 1, the action of each individual side of the apparatus is the same, as above described. The clutching devices foroperating the shafts 21 and 42 may be selectively operated at the proper times, so that one group of bars is transferred broadside by the left hand conveyer members 11 and 12, while the next group advanced on the central run-out is transferred broadside by the right hand mechanism, and .so forth, alternately. In this way the capaeit of the apparatus is reatly increased, ena ling it v to take care mill.

It will be clearly understood, moreover, that owing to the normal disposition of the ends of members 11,12 below the supporting 0 increased production by the surfaces of the rolls 1 and 6 respectively during the operation of said members, the

advancement of successive groups of bars or rods on the central run-oul, and the progrcss of other groups prcvibusly deposited on the side run-outs not interfered with or delayed Only when it is desired to pick a group of bars off the central run-out, are the inner ends of the members 11 and 12 raised above the rolls 1, and then only momentarily, sons not to interfere with the advancement of the next group of bars on said rolls. Similarly, only when a group of bars is about to be delivered onto one of the side run-outs, are the corresponding outer ends of the members 11, 12. raised above the rolls 6, and then they are lowered in order to effect the deposit of the group of bars on said rolls.

It will be noted that the bar or rod supporting surfaces of the members 11, 12 are made smooth, and for this reason, the sup porting surfaces of each set of rolls 6 are disposed slightly lower than the supporting surfaces of rolls 1, so that there will be no tendency for round rods'to roll back to the central run-out when being transferred broadside by said members. In other words, in normal positions. the members 11, 12 always slope downwardly from the central run-out in each direction and even when the outer ends of said members are momentarily raised, and the inner ends lowered, as shown at the left hand side of Fig. 1, the members are substantially level; in any case, the inner ends thereof are never lower than the outer ends.

It will be clear that the provision of independent operating devices for raising and lowering the extreme ends of the members 11, 12 on each side of the central run-out gives the operator the widest possible range of selection in controlling the broadside. transfer of rods or bars from the central run-out to the side feed tables. A group of bars may be transferred to either table desired, and the following groups may be transferred to the same or the other table wholly at the will of the operator. Moreover, if rendered expedient by a breakdown,

or congestion of bars on one of the side feed tables, a group of bars being transferred thereto by the corresponding transfer mechanism my be reversed in direction, by merely reversing the correspondlng motor 38, and may be carried past the central run-out onto the other feed table, as will be readily apparent.
